A stilbene synthase gene was isolated from Vitis vinifera.

Agrobacterium-mediated transformation of stilbene synthase gene (STS) from Chinese wild Vitis pseudoreticulata in Vitis vinifera L.

Construction of yeast expression vector and inducible expression of cDNA fragment of stilbene synthase in yeast;

Publications were reviewed in this paper,and was emphasis put on progress of research on stilbenes concerning its distribution,types,physical and chemical characteristics,biosynthesis,gene expression and modulation,stilbene synthase,gene transformation in plants and resistance to diseases.

This paper uses gene engineering technique to construct plant expression vectors of stilbene synthase gene appended by fruit special expression promoter,and introduces these vectors into agrobacterium strains LBA4404 and EHA105,and uses PCR and restriction enzyme digestion technique to identify these strains.

Aim: To construct a multi-PCR assay using specific primers of int1、 int2 and int3 to screen class 1,2 and 3 integrase (intI) among clinical samples.

Cloning and sequence analysis of RNA polymerase genes of H9N2 avian influenza virus strain isolated from Gansu;

Objective To detect the mutations in the hepatitis B virus polymerase gene and study effects of the mutations on lamivudine therapy.

A pair of universal primers were designed according to conservative regions of RNA polymerase genes of animal coronavirues published at GenBank,and used to amplify DNA fragment from cDNA of canine coronavirus(CCV),feline coron- avirus and other 6 coronaviruses.
